Description
Technical field
The utility model relates to Trackpad and panel display screen, is specifically related to the touch panel display screen.
Background technology
The flat-panel monitor that has touch controllable function at present constitutes with parts such as display screen, display driver, touch screen, touching signals detecting device, backlights, touch screen has resistance-type, condenser type, electromagnetic type, ultrasonic type and the photo-electric etc. of using different sensing principles, and display screen has TN/STN LCDs, TFT LCDs, OLED display screen, PDP display screen, CNT display screen etc.The flat-panel monitor that has touch screen is that the touch screen of split and display screen is stacked together, detects the planimetric position of touch point by display screen, makes the cursor on the display screen follow the location, touch point again.Stacked touch control type flat-panel display complex structure, complicate fabrication process, the thickening of making of touch screen and display screen becomes heavy cost increase; When touch screen places the display screen front, make between touch surface and display surface to have parallax, the reflection that the touch screen sensing electrode produces can make again and show uneven Uniform and show decrease of contrast under strong ambient light environment, influence display effect; Trackpad places after the display screen bottom surface, makes the contraposition difficulty of touchpad electrodes and display screen electrode, also can influence the brightness of demonstration.Trackpad and display screen being become one, make the flat-panel monitor with touch controllable function become more frivolous, is the direction that people make great efforts.
The integration mode of display screen and Trackpad is mainly stacked and inserted two kinds, stacked is to place Trackpad before the end face of display screen or after the bottom surface, display screen and Trackpad are independently born respectively and are shown and the touch-control task, Chinese patent (CN20010141451, MINXIANG INDUSTRY CO LTD, 2001), Finnish patent (FI19960002692, NOKIA MOBILE PHONES LTD, 1996), Jap.P. (JP19850161986, CANON KK, 1985), (JP19900095167, NIPPONTELEGRAPH ﹠amp; TELEPHONE, 1990), (JP19930306286, PFU LTD, 1993), (JP19980014850, NISSHA PRINTING, 1998), (JP19990142260, MIMAKIDENSHI BUHIN KK, 1999), Korean Patent (KR20000084115, YU HWAN SEONG; LIM JOO-SOO, 2000), (KR20020083301, BANG YONG IK; Etc., 2002), Taiwan patent (TW556141, AU OPTRONICS CORP, 2002), United States Patent (USP) (US6215476, APPLE COMPUTER, 2001), (US20030347603, TOPPOLY OPTOELECTRONICSCORP, 2003) etc. multinomial patent has all proposed resistance-type, condenser type, the Trackpad of electromagnetic type and the various stacked scheme of display screen, but Trackpad places before the display screen end face, can influence the display effect such as brightness, contrast, sharpness, color of demonstration; The electromagnetic touch-control plate places after the display screen bottom surface, makes the contraposition difficulty of touchpad electrodes and display screen electrode, also can influence the brightness of demonstration; And stacked method also can increase the integral thickness of display; The complexity of structure can cause reliability decrease again, and by the complexity of the complexity of production run and assembling also to making cost higher.
Inserted is that touch sensing is embedded in the display screen, at the other sensor (mostly being optical sensor) of settling of each display element, connect display element and sensor with dual electrode, difference transmitting and displaying drive signal and touch-control detectable signal, Korean Patent (KR20030019631, JUNG YONG CHAE; YANG DONG KYU, 2003), (KR20030077574, CHOI JOON-HOO; JOO IN-SOO, 2003), Deutsche Bundespatent (GB0304587.9, SHARP, 2003), United States Patent (USP) (US19970955388, SONY ELECTRONICS INC, 1997), (US19980135959, IBM, 1998), (US20030721129, EASTMAN KODAK CO, 2003) etc. multinomial patent has also proposed inserted scheme respectively, but touch sensing is inlaid into the manufacturing process complexity of display screen and dual electrode, the electrode outlet line difficulty, thereby also to making the cost height, and also may produce the mutual interference mutually of display drive signals and touch-control detectable signal.
Also the someone attempts to survey touch-control by the method for electric capacity between the box of surveying LCDs, as Taiwan patent (TW20020116058, LEE YU-TUAN, 2002), changes in capacitance is to cause that by touch-control pressure the thick variation of box produces between box, support between box makes the very big strength of the thick needs of the box that must change LCDs, and the box that changes LCDs is thick must influence demonstration, the dielectric anisotropy of liquid crystal material makes that again electric capacity changes with showing between box, get rid of that changes in capacitance can influence demonstration again between the box that the liquid crystal material dielectric anisotropy causes, so the method that electric capacity is surveyed touch-control between the box of this detection LCDs is worthless.
Find out a kind of scheme that solves above-mentioned complex structure, the manufacturing process difficulty is big, production run is complicated and assembles challenge, improve reliability, improve display effect, compressed thickness, reduce cost, realize that with succinct method the flat-panel monitor touch controllable function is necessary.
